blitToVManip: Check out-of-bounds using node position not index (#8127)

2019-01-25T19:01:00+00:00

Previously, when using 'place on vmanip' to add a schematic to a lua voxelmanip, if part of the schematic was outside the voxelmanip volume, the outside part would often appear in a strange place elsewhere inside the voxelmanip instead of being trimmed off. This was due to the out-of-bounds check checking the index. A position outside the voxelmanip can have an index that satisfies '0 <= index <= voxelmanip volume', causing the node to be placed at a strange position inside the voxelmanip. Use 'vm->m_area.contains(pos)' instead. Move index calculation to later in the code to optimise.

Fix warnings about dungeongen.cpp memcpy() and unused variable in MapBlock::deSerializeNetworkSpecific() (#8122)

* Fix warning about dungeongen.cpp memcpy() * Fix unused variable in MapBlock::deSerializeNetworkSpecific() * Fix unused variable a simpler way

Fix Mapgen Valleys getSpawnLevelAtPoint() (#7756)

2018-10-02T23:50:21+00:00

Fix various code issues found by cppcheck (#7741)

2018-09-23T19:12:39+00:00

Mapgen Singlenode: Remove 'flags' that duplicates a 'class Mapgen' member. Dungeongen: Initialise 'MMVManip *vm' to 'nullptr'. Inventorymanager: Remove assignment error 'found = '.

Change mapgen order to ores > dungeons > decorations (#7656)

2018-08-20T17:24:53+00:00

Previously dungeons > decorations > ores. Decorations depend on the node they are placed on, and ore types are increasingly able to place large continuous volumes of nodes, such as strata. Decorations are increasingly being used underground. The new order avoids a node being changed by ore generation after a decoration has been placed on it. The new order also avoids ores appearing in the walls of a dungeon if the wall nodes match the local stone node.

Mgv5: Change tunnel parameters to those of other mapgens (#7641)

2018-08-16T18:10:56+00:00

Make tunnels wider and use the noise parameters of most other mapgens. All other underground features are already identical to all other non-mgv6 mapgens, this final change modernises and improves the tunnels.

Fix build on gcc 5.0 (#7586)

Mgvalleys: Make river depth variation and humidity drop optional (#7532)

2018-07-18T02:34:05+00:00

Add 2 new mapgen flags to make river depth variation and humidity drop with altitude independently optional, instead of both being enabled by the 'humid rivers' flag. Simplify and clarify related code by removing a low priority optimisation regarding 't_heat'. Remove unnecessary optimisation bools and use spflags directly instead. Improve and fix documentation in settingtypes.txt. A few minor code cleanups.

Cavegen: Fix errors when getting biome outside mapchunk (#7480)

2018-06-26T18:35:23+00:00

Some cave segments are outside the mapchunk. Previously, biome was being calculated by a function that uses the noise maps. Points outside the mapchunk resulted in incorrect noise map indexes that were sometimes outside the noise map size, causing a crash. Use either noise maps or point noise calculations depending on point location.

Decoration API: Add lightweight ability to have complete coverage (#7456)

2018-06-24T16:14:18+00:00

When the noise value or fill_ratio >= 10.0 complete coverage is enabled. This disables random placement to avoid redundant multiple placements at one position. Instead, 1 decoration per surface node is placed by looping across each division. '10' was chosen as this is the fill_ratio that previously created very near complete coverage. The complete coverage feature therefore integrates smoothly when noise is used for variable decoration density. 'fill_ratio = 10' should be used by modders who want a decoration placed on every surface node. Compared to before such a decoration placement will be 10 times faster.
